After repeatedly seeing questions around failed connections to HANA Express, I’m compiling the basic troubleshooting steps I take when, for example, HANA Studio does not connect to my HXE instance. The most typical error is:
The system cannot be reached. logon data cannot be used.
The order in the steps is not random. If any of the tests fail, moving forward with the next step does not make any sense without fixing whatever is causing the test to fail.
Is the database running?
Sounds obvious but worth checking.
From the console in your server, you can use ./HDB info and make sure you can actually connect using hdbsql -i -d Properties–>JDBC trace:
Options for other clients can be found in the help.
Further help, as usual, can be found in the Q&A. Be sure to search for your question before you post it and add all the information you consider relevant (what error you are getting, what have you already tried and failed, some screenshots).
